SPECIFICATION forming part of Letters Patent No. 760,227, dated May 17, 1904.

Application filed November 12, 1903. Serial No. 180,821. (No model.)

To (:l/ZZ whom it pea/y concern.-

Be it known that I, FAY H. MARTIN, a citizen of the United States, residing at Hydepark, in the county of Norfolk, State of Massachusetts, have invented a certain new and useful Improvement in Fliers for Roving-Machines, &c., of which the following is a speci fication, reference being had therein to the accompanying drawings.

The invention has relation to the fliers off roving-machines and the like machines, and in particular to the pressers of such fliers. More especially it has reference to the means and manner of combining the said pressers with the presser-carrying arms of the fliers.

In a flier of the class to which the invention relates the presser instead of being piv oted in ordinary manner upon the pressercarrying arm, so that the center of the pivot constitutes the axis or center of the are which is described by the presser-shoe in its move ments, is mounted upon the arm in such a manner that as the load of roving which is being wound upon the bobbin Increases 111 "diameter and presses the shoe of the presser outwardfrom'the' spindle the presserin addition to swinging outward in aradial direction is caused to move bodily in the direction of its length. The result of causing this move ment bodily in the direction of its length to constitute a component of the movement of the presser in-the operation of the flier is to cause the shoe of the presser to travel inward and outward in a substantially horizontal direction and to stand at the same height when in its outermost position as when it occupies 'its innermost posltion.

Thereby any noticeable irregularity in the positioning of the ends of the successive layers of roving which are wound upon the bobbin is obviated.

The especial objects of the invention are to provide in a flier of the type which has just been described a simple, practical, and inexpensive construction of means for supporting the presser upon the carrying-arm of the flier and controlling the presser in its movements and to provide a construction in which the tendency to wear is reduced to a minimum indicated by the dotted line A I in Fig. 1 looking in the direction that is indicated by the arrows at the opposite end of the said-line. Having reference to the drawings, 1, Fig. 1, designates the spindle of a roving-frame, 5 the upper portion thereof being indicated by dotted linesin the said figure. 2 is a bobbin surrounding the said spindle. 3 is a flier which is applied to the said spindle. The boss or nose of the flier is shown at 31. The 7 balancing-arm of the flier is designated 32 and the arm to which the presser-finger is connected is shown at 33;

A isthe presser-flnger; 41, its weight-arm; 42, the p'resser-shoe, and 43 the guide-opening of said presser-shoe, through which the roving is led on its way to the bobbin. The body of the presser-finger has two slots 4.4; A l formed therethrough. The said slots stand at an inclination or angle with respect to each other. Blocks or bushings 5 5, carried by the arm 33, are received within the slots 44 44: and support the presser-finger, and by the contact of the opposite sides of the slots with the exterior portions of the said blocks or 5 bushings the presser-finger is positioned and also controlled radially in its movements. The opposite faces 45 46 of the portion of the said body in which the slots 4:4; A4.- are formed are fiat and parallel with each other. One of 9 the said faces-namely, that which is marked .5fits against a flat bearing-surface 331, which is formed upon the proximate side of the arm 33 of the flier, the said face 45-working in contact with the surface 331 in the movements of the presser-finger. A cap-plate 6 is located at the outer side of the presserfinger and is secured in place by means of screws 7 7. The said cap-plate contacts with the outer face 46 of the presser-finger and serves to keep the presser-finger in place upon the blocks. The presser-finger is guided laterally by the inner face of the said cap-plate and the opposing bearing-surface 331 on the arm 33 of the flier. The positions of the slots 44 44 are such as to enable the presser-finger to swing or move in a radial direction and to cause the presser-finger while moving radially to move also bodily in the direction of its length, so that the shoe of the presser shall travel inward and outward in a substantially horizontal direction, as previously mentioned. In the illustrated embodiment of the invention the slots are formed and positioned so as to cause the presser-finger to swing or turn about a center of motion which is located, as

. indicated at m, Fig. 1, ata point in the neighpresser-finger is shown in full lines in Fig. 1,

with the shoe thereof occupying the innermost position of the said shoenamely. in contact with the periphery of an empty bobbin 2, the said bobbin being shown in full lines. The said figure shows in dotted lines the outline of a full load of roving wound upon the said bobbin. Preferably the slots 44 44, which are formed in the body of the presser-finger, are curved, and the opposite sides of each of the blocks or bushings 5 5 are flattened to work in contact with the sides of the corresponding slot 44.

In conformity with the invention the blocks 5 5 are formed of separate pieces, which are removably applied to the arm 33 of the flier. The arm 33, which is tubular to permit of the passage of the roving therethrough on its 1 way from the boss or nose 31 of the flier to the lower portion of the presser-finger, has formed thereon projecting hollow studs or nipples 34 34. The blocks or bushings 5 5 are mounted upon the said hollow studs or nipples, which latter are internally screwthreaded. The stems of the screws 7 7 pass through holes 61 '61, which are formed through the cap-plate 6, and also pass centrally through the blocks or bushings 5 5, and their inner ends enter the hollow studs or nipples. By the engagement of the threads of the said screws with the internal threads of the said hollow studs or nipples the cap-plate and blocks or bushings are held properly in position, The hollow studs or nipples are formed integral with the arm 33 of the flier, they being produced by casting the flier with enlargements upon the side of the said arm and subsequently milling the said enlargements exterioi'ly down to the proper size and shape, boring them, and'internally threading them. The said hollow studs or nipples serve a twofold purpose. In the first place they constitute supports for the blocks or bushings 5 5, by which the latter are held in proper position. In the second place they afford proper support for the inner ends of the securing-screws 7 7 and enable a sufficient length of thread to be provided for engagement with the said ends of the screws. The wall of the tubular arm is too thin to permit of being properly screwthreaded. The blocks or bushings 5 5 are bored, as at 51, for the passage of the securing-screws 7 7 therethrough. They are also counterbored, as at 52, to enable them to be fitted upon the exterior of the hollow studs or nipples. The said blocks or bushings enable more bearing-surface for contact with the sides of the slots 44 44 to be provided than conveniently possible in the case of screws or rivets.- They are conveniently removable and renewable after wear occurs. Studs or rivets which have been employed heretofore in the like position wear through the action of the presser-finger and permit the latter to become loose. The said blocks or bushings also constitute distance-pieces by means of which the cap-plate is held separated properly from the side of the arm 33 to prevent'the presser-finger from binding in its movements. The capplate 6 covers the slots 44 44 at the outer side of the presser-finger. while the flier is in actual operation and serves to exclude dust or lint from the said slots. It constitutes also a distance-piece by means of which the outer ends of the securing-screws 7 7 are held in the proper positions-that is to say, whereby the said outer ends are kept at the proper distance apart and are prevented from becoming bent or sprung. In some embodiments of the invention the screws 7 7 may be replaced by rivets or other substitutes; but preferably I employ screws. because they admit of being removed for the purpose of renewing worn parts whenever required. v r

I claim as my invention- 1. The combination with the flier-arm, and the slotted presserdinger, of the blocks or bushings within the slots of the presser-finger, securing means passing through the said blocks or bushings and connecting the latter with the flier-arm, and means to confine the presser-finger upon the said blocks or bushlngs.

2. The combination with the flier-arm, and the slotted presser-finger, of the blocks or bushings within the slots of the presser-finger, the cap-plate at the outer ends of the said blocks or bushings, and securing means passing through the cap-plate and blocks or bushings and securing the said parts together and to the flier-arm.

3. The combination with the flier-arm provided with the hollow studs or nipples, and the slotted presser finger, of the blocks or bushings fitting the said studs or nipples and occupying the slots of the presser-finger, the
